What conclusion can be drawn about the necessity of water for living organisms?

• A. Only plants need water for survival
• B. Animals use water less than plants do
• C. Life cannot exist without water
• D. Water is optional for many organisms

Answer: (C)

The conclusion that life cannot exist without water is fundamentally supported by the role water plays in biological processes. Water is crucial for cellular functions, acting as a solvent for biochemical reactions, transporting nutrients and waste, and helping to regulate temperature in organisms. This dependence on water is evident across all forms of life, including plants, animals, and microorganisms. Without water, essential processes such as respiration, digestion, and photosynthesis would be disrupted, leading to the inability of organisms to survive. This underscores the universal requirement of water for sustaining life, unlike the other options which suggest a lesser importance of water for various organisms.
